I recently brought home a massive motor and flywheel and am going to set it up as just a flywheel for my combined energy project. This is just the beginning of a big project.
I am going to start with some of the math.
I am pretty good at some math but would like help making sure I get things right with this project
So far I found some pretty good math on line but have never used this exact kind of math before. The math I found is this
Physics:
Stored energy = sum of kinetic energy of individual mass elements that comprise the flywheel
Kinetic Energy = 1/2*I*w2 , where
I = moment of inertia (ability of an obeject to resist changes in its rotational velocity)
w = rotational velocity (rpm)
I = k*M*R2 (M=mass; R=radius); k = inertial constant (depends on shape)
Inertial constants for different shapes:
Wheel loaded at rim (bike tire); k = 1
solid disk of uniform thickness; k = 1/2
solid sphere; k = 2/5
spherical shell; k = 2/3
thin rectangular rod; k = 1/2
I need to do this for both the rotor and the flywheel so I can find out how much horse power I will have to have to get it moving and up to speed.
The flywheel weighs 6920 pounds.
The rotor now weighs 6120 pounds.
The shaft weighs 3580 pounds.
